.10 Claims.

This invention relates to improvements in amusement apparatus,particularly a novel form...

of bowling game, one of the principal objects being the provision ofelectrically operated control and score indicating and registeringmechanism arranged to alord the scoring typical of the regulationbowling game. l

Viewed from anotheraspect, it is an object to provide a bowling game inwhich the pins are replaced by projections of light directed onto thealley in the customary triangular array or spotting arrangement,together with a scoring switch associated with each spot of light andelectrically -actuated score registering and indicating mechanismconnected with the scoring switches in such manner that the player mayplay one line consisting of five frames of two balls each, making atotal of ten balls, the arrangement further be- 2 lng such that eachbrace of balls is capable oi effecting a strike, in which all oi thepins or spots are struck; or a spare, in which all of the pins are'struck by the use of two balls; or the striking of individual pins willbe registered and indicated cumulatively, it being possible to achieveand register the top bowling score of 300.

A further object is the provision of score indicating and registeringmeans in a game of the class described and which is capable ofindicating the lseveral possible bowling scores heretofore alluded toand which is nevertheless of relatively simple construction andoperation.

Yet another object is theiprovision in a game of the class describedincluding :ball-operated score switches or the like, of means forregistering or indicating score values achieved by balls when played ingroups. the group consisting, for example, of two balls, and thearrangement being such that the score indications will be those peculia1;,-.to the regulation game of bowling in so 40 far as the value of thescore may vary dependent upon the order in which score objectives areachieved in playing the two balls of the group, that is, for example,depending upon whether the first ball of the group itself achieves themaximum score or whether the maximum score is achieved through the useof two balls, each of which may variously achieve part of a cumulativescore. v

Still another object is the arrangement in a 50 ball rolling game, ofscore switches adapted to be actuated by a played ball, and tallyswitches arranged in a ball return runway for engagement by a spent ballto set up various circuits which will operate mechanism to register andindicate the score achieved.

(o1. 27a-11s) j A sun further object is the inclusion in the varrangement of tally switches oi certain master tally` switchesconnected with score indicating and registering mechanism so that thelatter will 5 be conditioned by the rst ball of a group, if the maximumscore is not achieved by the first ball, so that the subsequent ball orballs Vwill operate the tally Aswitches to totalize the score achievedfor each group of balls played.

Other objects, advantages and novel aspects 10 of the invention residein certain details of construction as well as the cooperativerelationship of the component parts of the illustrative embodimentdescribed hereinafter in view of the annexed drawings', in which: 15

The particular bowling game employed to illustrate the novel circuitconnections and control mechanism constituting the present inven- 30tion, is that described and claimed in my U.- S. Patent No. 2,194,830,which patent includes as one vof its novel features the substitution ofprojected light for the tenpins employed in the usual bowling game, thisnovel arrangement including means for projecting spots of light onto thealley in the positions usually occupied. by the tenpins in the customarytriangular racking thereof, the spots of light, in this sense,constituting the pinsat which the bowler directs his ball and certain ofthe pins orspots of light having associated therewith a score switchwhich will be engaged by a skillfully bowled ball to actuate scoreregistering means.

Such a game is illustrated in Fig. 1, and includes analley or ballrolling board I0 upon the underside of which are secured a plurality ofi scoring switches SS, and each switch being provided with an operatingfinger I la, I I b, etc., Projecting through the board in a positionwhich would correspond to that occupied by the bottom of one of thebowling pins when racked or spotted in the customary manner.y As willhereinafter appear, all ten of the bowling pins are not provided withscore switches.

The scoring switches and their specially positioned operating ngers eachconstitute part of a ball objective, each of which is completed in thepresent instance by the provision of means inthe form. of lamps I2situated in a housing I3 above the alley, together with a projectingaperture I4 for each lamp for directing a spot of light S (Fig. 2) ontothe alley I0 in the area occupied by one of the switch operating ngersIIa. Thus, each of the switch operating fingers IIa, IIb; etc., and itscorresponding spot of light S, constitute a ball objective, or, in thepresent case, a bowling pin.

'Ihe arrangement is such that a ball bowled atthe pins will actuatecertain of the scoring switches and the associated control mechanism, sothat the light I 2 corresponding to each scoring A switch struck, willbe extinguished, and an indication of the score thus achieved willultimately be indicated upon a score panel I5.

The game is preferably arranged for coincontrolled operation vandincludes a coin slide I6 requiring the deposit therein'of a coin to freethe slide for reciprocation to, actuate certain master circuit controlmeans and to release the bowling ball B for movement from confinementbeneath the board .through a ball return or delivery alley I 'I (Fig. 3)into a transversely directed gutter I8 at the front of the board beneaththe coin slide.

It should be observed that the ball playing lboard or alley I 0 isinclined from the front of-` the machine, at which the coin slide'issituated,l

toward the rear where the pins are situated, so that the bowling ballwill ultimately ilnd its way into a rear transverse runway I 9 inclinedto direct the ball into the return 0r delivery alley I.'I. When the ballhas been bowled a predetermined number of times, mechanism' is operatedautomatically to block the movement of the ball to the return gutter sothat it becomes necessary to deposit another coin to free the ball.

The circuit connections and mechanisms for `exercising control over thegame and registering the scores achieved, are illustrated in the circuitdiagram of Fig. 6, which is to be read with convenient reference to thestructural illustrations shown in Figs. 1 and 3, particularly. Fig. 6illustrates the condition of the circuit control means when the game isready for play, and therefore assumes a previous operation of the coinslide I6, and in this-condition the cut-off means which ordinarilyblocks the return of the bowling ballv B to the player, is latched toremain in ineffective condition until the. ball has been bowled tentimes, constituting one line or ve frames of play. y

At this time the several projecting lamps I2 are illuminated so that allof the light spots S are visible to the player, who seizes the ball Bfrom the return gutter I8 and bowls it skillfully at the array of lightspots in an effort to hit the king-pin, that is to say, the foremostlight spot S in which the king-pin switch operating linger IIa isdisposed. This play, if successful, constitutes a strike correspondingin regulation bowling to the knocking over of all ten pins, andeffecting, in the present instance, the extinction of all lamps I2 withan appropriate score indication set up on the panel I5 by theilluminated score lamps.

The circuit connections involved in the indication of a strike followingthe operation of the king-pin score switch operating finger IIa,

aaaaaszs connects. batterydrom a power source via contact 20 on #Ilocking switch, causing the latter to release, with the result that acontact 2| in the bank of contacts thereofx will connect power through acontact 22 on the second locking switch to release the latter.` Inaddition, anotherA power connections established through contact 25 onthe #2 switch through contact 26 on the #4 switch energizing the latter;contact 2'I on the #2 switch through contact 28 on the #5 switch toenergize the latter; contact 29 on the #3 switch through contact 30 onthe #6 switch energizing the-latter; contact 3| on the #4 switch throughcontact .3 2 on the #l switch energizing the latter; contact 33 on the#6 switch through contact 34 on the #I0 switchenergizing the latter;contact 35 on the #I switch via. conductor 36 and contact 31 on thespare locking switch SPenergizing the latter. The strike locking switchST also pulls up as a result of power connected thereto via conductor 36from contact 35 of the #I locking switch. f v

As one oi' the results of the energization of the coils for the gang oflocking switches, all of the spot projecting lamps I2 are extinguished,this being accomplished by the breaking of power circuits for each lampthrough contacts I2a, |212,`

IZc, I2i, one of which is associated with each of the locking switches#I to I0. Alsor the vstrike indicating lamp 40 is energized through acommon power conductor V4I and a contact 42 on the bank of the strikelocking switch; a contact 43 also common to conductor 4I, energizes agong or signal means 44.

It may be observed that while the spare switch SP was released, alongwith the other locking switches, theV spare lamp 45 is not energizedalthough the energizing contact 46 therefor is closed with a. connection41 to one of the normal contacts on the strike switch which connectspower to the spare lamp through contact 42, since the latter has beenpulled away from its normal contact by release of the strike switch. Itmay be observed that the gang of locking switches including the spareand strike switches is normally set or locked in the condition shown inFig. 6 and that the energization -loi' the several coils through theserial connections heretofore indicated, causes the several switches tobe released from the condition shown in Fig. 6.

Means for registering-the score which results from making a strike andthe release of the gang returning ball is a counting switch TC whichconnects power via a conductor 50 tothe coil BC of a ball countingcommutator or stepping switch, the serial contacts of which areconnected with ball indicating lamps BL to which power is connected bythe wiping contact arm WC responsive to the successive energizations ofcoil BC as each of the ten balls is returned to the player. By thismeans, the player is apprised of the number of balls he has played. Thereturning ball thereafter successively engages the operating iingers ofthe tally switches numbered ordinally I to I0 (TI TIO) which areconnected to a common conductor 5I through a contact MX on a masterlocking switch ML to energize the coil UC oi.' a units counter,` thewiping contact arm WU of whichv is rnovablesuc` cessively to connectpower to the units indicating lamps UL which designate the values-of theindividual pins The remaining terminal of each of the ordinal tallyswitches is connected with a contact in one of the locking switches sothat it is necessary to release the latter in order to render thecorresponding tally switch effective.

In the circuit diagram it will be observed that switch TI will beenergized through contacts 35 of the first locking switch, the remainingtally switches being conditioned through similar connectlons as follows:T2 through contact 52 on the #2 locking switch; T3 through contact-53 onthe #3 switch;v T4 through contact 54 on the #4 switch; T5 throughcontact 55 on the #5 switch; T6 through contact 56 on the #6 switch; T1throughcontact 5I` on the #1 switch. T8, however, is common to TI and is-thereforeconditioned by the #l locking switch, while T9 is common to T6and will therefore be conditioned by the #6 locking switch. The lasttally lswitch TIIL is conditioned by a contact 58 on the #I0 lock. ingswitch.

Thus, if locking switches #I to I0 have been pulled up as aforesaid,each ofthe series of tally well as the strike and spare switches foroperation by the returning ball.

In addition to the units counting switch, there is a ten's countingswitch of'similar structure and including a coil BT which may beenergized throughya contact MY on the'master lockingx` switch, thiscontact being connected in common to the spare tally switch TS and thestrike tally switch TSt, which arev respectively situated at a lowerlevel from the ordinary `tally -switc es toward the end of the ballstravel. Since both the spare and strike locking switches are released bythe achievement of a strike as aforesaid, the spare tally switch TS willbe connected wi power through a contact 60 on the contact ba k of thespare locking switch. Likewise, the strike tally switch ISt is connectedwith power through a contact El on the strike` locking switch ST.However, operation of the latter two tally switches by the returningball will not be effected unlessv the master locking switch contact MYis iirst closed.

Release ofthe master locking switch in the case of a strike by the firstball, is eiectedby the closing of a contact 62 on the strike lockingswitch which is effected the instant the latter is released when thebowler makes a strike. In consequence of this release of the masterlocking switch, all of the tally switches TI to TID, TS, and TSt areoperated by the returning ball and as aresult the units counter switchis energized ten times, which will result in the illumination of the rsttens lamp on the tens counting lamp bank, since switch 83 is energizedwhen closed on the tenth step of the units counter to energize coil BTonce, this coil being energized twice more as a result of the closing ofswitches TS and TSt by the same returning ball, so that a total score of30 will thus be indicated to the player, the #I ball counting lam alsobeing illuminated.

In order to prepare the control circuits for` the second ball of theframe or group, the gang of locking switches, as well as the masterlocking switch, must be reset for the purpose, among other things, ofilluminating the spot projecting lamps I2 and extinguishing the strikelamp 4I). Such resetting is controlled by the ball effecting ating areset tally switch TR near the lower end` of the return alley to connectpowervia the now closed contact 63 on the master locking switch whichenergizes a holding relay I-IR` locking a circuit for the latter throughcontact E and contacts 64 on the holding relay, another contact 65 ofwhich energizes the resetting solenoid PR.

As shown in Fig. 3, energization of solenoid PR pulls back a slide barlili setting a dashpot 6l to regulate a slow return of the slide bar byits spring 68. Retraction of the bar fromthe nor-N mal position of Fig.3, causes contact E to open, thus releasing the locking circuit to theholding relay.

When the master locking switch was released, a circuit was set up by itscontact 69 to the normally open contact D on the master resetting switchto connect power to the coil MR to reset the master locking switch,contact D being closed as soon as th-e resetting solenoid PR pulls up.Meanwhile. the last of the tallyswitches `has been rendered ineffectiveby theopening of the master resetting contacts C.

As the resetting slide 66 is drawn back by sole,- noid PR, anover-and-under arm 'Ill thereon passes over a gang reset switch GS andon the return stroke of the slide, the arm 'I0 is peculiarly constructed"to close this switch momentarily and energize the gang reset solenoidGR. which is mechanically connected with all of the locking switchesexcept the master locking switch, to restore the same -to their lockedor set condition. When this is done, the apparatus is in its resetcondition preparatory to the bowling of the next frame\or brace ofballs, the holding relay HR being released and the master locking switchbeing set, all as shown in Figf, the spot `projecting lamps I2 againbeing illuminated.

The bowler retrieves the ball B from the return gutter I8 and againpropels it at the light spots and associated scoring switches, and thistime it will be assumed that he misses the king-pin and strikes the #3pin" and operates the associated finger IIc and the vcorrespondingscoring switch, which results in energizing the #3 locking switchthrough its contact 24, thus releasing the same to extinguish thecorresponding lamp I2 by opening its switch I2C and further eneron the#I switch and contact 28 on the it."V

.gung the #s lacking switch through Contact 'n switch, so that the lampI2, which corresponds to #I or #5, opens a series power circuit throughall of.. the locking switches after the iirst for the strike switch.This series circuit includesv a connection 13 lwith one side of thepower line extending through contacts 14, 15, 16, 11, 18 19, and 80 to8| onA the strike switch. each of the contacts 14 through 80 beingassociated with one of the locking switches #2 to #IIL Thus, release otany locking switch after the first, will disable the strike switch.

It will be observed that the pin (Fig. 5) is lnot provided with a scoreswitch, and the pins" in positions l and 9 are similarly arranged, thecircuit connections being such that the scoring switches associated withcertain "pins control the projectingv lamps and locking switches forcertain other pins;V for example,

the king-pin controls all lamp circuits, and the #I pin controls its owncircuit and that for the #I and #5 pins. Similarly, the #2 "pin controlsits own lamp circuit anciV that for the #l and #5 pins, while the #6 pincontrols its own circuit and that for the "pins in positions 5 and I8.`

The shaded areas in the diagram of Fig. 5 illustrate the groupingcontrol of the score switches, it being pointed out that the #4 pinswitch also controls the circuits for pins in positions 1y and 8.

Thus, the bowling of the iirst ball in this illustrative example causedthe extinction of the lamps for pins 3, 5, 8, 9 and III, and alsodisabled vthe strike locking switch. By the same token.. the\#2 `scoreswitch would control the circuits for pins 4, 5, 1 and 38.

The -spent ball which accomplished this scoring in traversing the returnrunway will actuate the ball Ycounting switch TC and step the ballcounter register or switch to the next position so that the registerwill now indicate a .total of two balls bowled. However, the remainingtally switches are not conditioned to eilect the score registers byreason of the open condition of -en`ergizing ML to release the masterlocking switch and set up a totalizing or tallying circuit for thesecond ball of the group or brace.

Assuming next that' the bowler bowls the remaining ball of this frame orpair and that he is successful in making a spare, which is equivalent toknocking down all of the remaining "pins and which would thereforerequire a strik- Ving oi the #I pin to operate its switch IIa, toextinguish the lamps for the #L 2, 4, 1 and 8 positions, such action bythe bowler will result in release of locking switches numbered I to I0,as well as the spare switch SP, thereby conditioning tallying switchesTI to TIII, as well as TS1, for operation of the registering means.

It will be recalled that the ilrst ball eiiected release of the masterlocking switch. Subsequently the passage of the spare ball through thereturn alley will operate the counting switch TC and all of the tallyingswitches TI to TIO, as well as switch TS. al1 of which are now finallyconditioned by the release of the master locking switch to step theunits counter and tens counter to indicate a score equivalent to aspare. Therefore, the units counter will be stepped ten times and on thetenth step will step the tens counter once through switch 83, and thetens counter will be moved an additional step by the ball closing switchTS, thus setting up a score of 20 for the spare onk the tenscounter.Upon leaving the return alley, the spare ball will trip the reset tallyswitch TR, energizing the holding relay HR through contact 63 on MLenergizing the resetting solenoid PR through contacts 64 on HR andcontact E on the slide switch, which again retracts the resetting slide66 which operates the gang switch GS and solenoid GR to reset the gangof locking switches and which also opens the locking 4circuit for HR andcloses the slide switch D tol energize MR and reset -the master lockingswitch.

Having described the manner in which a strike and a spare are scored andregistered on the apparatus, a third scoring possibility can be handledby the control mechanism and contemplates a. conditionwhere the bowlerdoes not make a strike or a spare, but is nevertheless accorded thecumulative value of pins he may have knocked over, in a manner ofspeaking. Assuming that after the accomplishment of a spare and strikein the manner aforesaid, the associated .mechanism has been restored tothe condition exempliiied in Fig. 6 and that the bowler 'strikes the"pin at position 6, the individual score value of the pins struck willbe stored up and indicated, it being recalled that the #6 locking switchexercises control over the lamp and locking switches associated withpositions 6, 9 and .III (the same being true of positions l and 8 and1). In the present example, tally switches Sand 9 and I9 would beconditioned to operate the registering switches, and the rst ball of thepair which was responsible for extinguishing the lamps for positions 6,9 and I0, would, in leaving the return runway, close the master tallyswitch to release the master locking switch, thus closing.

contacts MX and MY to the units counter and tens counter. Thereafter, itmay be assumed that the remaining ball of the pair is successful instriking the scoring switch at position 1, which would result in releaseof locking switch #1 and conditioning tally switch T1 for eiectiveoperation.

'I'he second ball in traversing the return runway would operate tallyswitches TC, T6, T1, T9, and TIII, all of which would result in steppingthe ball counter once and the units counter four times. the controlcircuits as heretofore described, leaving a score of 4(disregarding anyprevious score) indicated by the units counter and the lamps associatedtherewith, and the player is ready to bowl the next frame.

Continuing the foregoing example, it is now assumed that the playerbowls again and strikes the "pin at #3 position, with a consequentextinction of the lamps illuminating positions 3, 5, 6, 9 and III,having a total score value of 5 units, and upon-'bowling the remainingball of the pair, it is further assumed that the pin at #1 position isagain struck, all of which results in conditioning tally switches T3,T5, T6, T1, T9 and TIG to operate the units counter in the usual manner.Since the units counter was stepped four times from its initial positionas shown in Fig. 6, and sinceI the bowling of the next frame In leavingthe runway, the ball will resetk Vresulted in a reward of 6 units to theplayer, the score registering will be transferred automaticallyfrom thetens counter, it being observed that when the wiper WU reaches thecontact point numbered I8 on the units counter, a circuit is establishedfrom the wiper via this contact and a conductor 82 to a transfer switch83 forming part of the units counter and closed by the ratchet operatingarm 84 thereof each 4 time the coil UC is energized, with the resultthat the tenth impulse to the units counter will be transferred byswitch 83 to the coil BT of the tens counter, causing the `latter to bestepped once.

It may be observed that the stepping switch employed for units countingis adapted for continuous and unidirectional movement, thisbeing'illustrated by the provision in the units counter of a second bankof counting contacts indicated at 84', these banks of contacts beingrepresented in a direction clockwise around the dial and being shownonly in part for purposes of simplification.

When the player completes five frames or has bowled his tenth ball, thewiper contact WC of the vball counter switch will have been stepped tentimes, carrying the wiper against a cut-off switch CS closing the sameto connect power to a contact 85 of switch G to energize the ballcut-off solenoid CO, switch G being permitted to close when the ballcut-off slide 86 is latched in retracted condition by latch arm 81,following operation of the coin slide. Energization of CO withdraws thelatch 81 and permits cut-olf slide 86 to be restored by its spring 89 toproject a cut-off arm 90 across the return alley i1, block` ing movementof the ball to a position of access to the player, who must now depositanother coin to continue the play.

To release the game for play, a coin is deposited in slide I6 and thelatter is pushed inwardly to the limit of its stroke, which results inthe closing of three resetting switches AI, A2, and A3, eachrespectively in circuit with a resetting coil CR. for the ball counter,one of contacts 84 for the units counter, and RT for the tens counter,these switches being normally biased to open condition, as shown inFigs. 1 and 3, by engagement therewith of an arm 8| rigid with the coinslide. This arm also actuates a time switch 92 included in the mainpower line to maintain the apparatus in operative condition for alimited period so that the game cannot be monopolized unreasonably for asingle coin. The inner end of the coin slide is adapted to bear againstan oiset 93 on the resetting slide 66, thus opening switches C and E andclosing switch D to reset the master locking switch ML and also tooperate the gang switch for the gang reset solenoid, which restores allof the locking switches. Thus, the master locking switch will bedisposed in the condition shown in Fig. 6, and the wiper arms on thestepping switches BC and BT will be restored yby the usual spring meansto their initial positions as a result of the release of theircorresponding locking pawls 95. The units counter will advance to thenext zero position by reason of current owing through switch A2, contact84 into wiper WU', which is associated with the bank of contacts 84',and thence into step-up solenoid UC.

Operation of theV coin slide as aforesaid also results in energizationof the ball release solenoid BR by a circuit through switches F and D,slide 88 being automatically latched in retracted condition by arrn 81until the latter is tripped after the tenth ball.

The registering switches are arranged to give an indication of 300points which is equivalent to the customary perfect bowling score. Inorder to simplify the illustration and description of the device. someof the score indicating lamps have been omitted. j
